Krusty’s Fun House is a 1992 puzzle-platformer developed by Audiogenic for the Game Gear. Playing as Krusty the Clown, you must navigate through a series of rooms in the infested fun house, figuring out how to direct marching rats into extermination traps operated by other familiar characters from The Simpsons. It blends standard platforming action with thoughtful routing puzzles.
How to play
Your objective in each level is to eliminate every rat by creating a clear path for them to march blindly into a rat trap. You can pick up and place blocks to build stairs or block off wrong turns, while avoiding enemies like flying pigs and snakes. Use the arrow keys to move Krusty, press X or Z to jump, pick up, and throw blocks, and press Enter to start or pause the game.
Tips
- The rats always walk forward until they hit an obstacle, at which point they turn around. Use this predictable behavior to construct safe corridors out of blocks.
- Survey the level layout carefully before releasing the rats or changing their path, as one misplaced block can cause them to walk off a ledge or wander in the wrong direction.
